Paper Towel Dispenser ("Look Mum, No Hands")

I needed a one hand operated paper towel dispenser when cleaning SLA prints.

Fits a 180 mm diameter roll with an inner diameter of 45 mm. The heavy rod keeps the paper in place and helps to tear away individual sheets. For heavier paper or non perforated rolls an optional saw blade can be inserted.

The assembly needs two M4x16 mm socket head screws and two M4 nuts. A thin washer can be added between both parts.

Printed with PLA with a 0.3 mm layer height and minimal infill. Snug supports are needed for the threads only.

Updates:
1) Modified the blade position. Now in front of the rod. (v19)
2) Added a version without the saw blade slot. (r2 v2)
